I got the KTM Supermoto stand, Part #59229055000 and it works good. I can't seem to get both the wheels off the ground at the same time though. It's either one or the other depending on where exactly the stand is under the engine.
The engine has some flat "ribs" that sit perfectly on the stand. I'm not sure how well this stand will work for ya, but for general cleaning of the bike, especially when just rotating the wheels around, it works great for me!
